1) To see answers to things you posted:
Click on your name (upper right, next to "Welcome").
Click on "Statistics" near the middle.
You can then go directly to posts you made or threads you started, and see how what folks have been adding.
2) To see "personal" messages:
Click "Private Messages" under your name, again upper right.
You should see anything you sent or received.
And, just so you know, some of us enjoy some good-natured ribbing when we see a typo or spelling mistake. It's not personal, just something we do when we're bored.
